Compounds of phosphinanes and azaphosphinanes, a process for their preparation and pharmaceutical compositions containing them

ABSTRACT

Medicinal products containing the same which are useful in treating conditions requiring a TAFIa inhibitor.

The present invention relates to new compounds of phosphinanes and azaphosphinanes, to a process for their preparation, and to pharmaceutical compositions containing them.

The compounds of the invention are TAFIa (activated thrombin-activatable fibrinolysis inhibitor) inhibitors.

TAFI (also called plasma procarboxypeptidase B, procarboxypeptidase R or procarboxypeptidase U) is a plasma glycoprotein of 60 kDa produced by the liver, which circulates in the form of a zymogen. During blood coagulation and fibrinolysis, thrombin and plasmin cleave the pro-segment of TAFI in the region of the Arg92-Ala93 bond and convert it into an active enzyme, TAFIa, the half-life of which is from 8 to 15 minutes at 37° C. Cleavage of the pro-segment by thrombin is accelerated by thrombomodulin, a cofactor which is present in plasma and at the surface of vascular endothelial cells (Bouma B N and Meijers J C, Thrombin-activatable fibrinolysis inhibitor, 2003, Journal of Thrombosis and Haemostasis, I: 1566-1574). TAFIa regulates fibrinolysis negatively by cleaving the C-terminal lysine residues of the fibrin fibres which appear during the partial degradation of fibrin by the first traces of plasmin. These C-terminal lysine residues on the partially degraded fibrin behave like ligands of the circulating plasma plasminogen and of the tissue plasminogen activator (tPA) generated by the endothelial cells during thrombotic ischaemia. They thus permit localisation of the conversion of plasminogen to plasmin by the tPA without interference either with the circulating plasmin inhibitor α2-antiplasmin or with the circulating tissue plasminogen activator inhibitor (PAI-1). Cleavage of the C-terminal lysine sites by TAFIa therefore reduces the rate at which plasmin is generated. Endogenous fibrinolysis is then inhibited and lysis of arterial and venous fibrinous thromboses as well as therapeutic thrombolysis undertaken in patients in the acute post-thrombotic ischaemic phase are likewise diminished. TAFIa inhibitors therefore have the potential to increase endogenous and therapeutic fibrinolysis and to behave like antithrombotic and profibrinolytic agents without the risk of major haemorrhage, since they do not interfere either with platelet activation or with coagulation during blood haemostasis.

The property of inhibiting TAFIa therefore makes it possible to envisage using the compounds of the invention in the treatment and prevention of thrombotic events in at-risk patients.

Their use will be valuable in the treatment, prevention and secondary prevention of vascular complications, more especially cardiovascular, pulmonary and cerebrovascular complications, associated with atherothrombotic diseases, with atherosclerosis, with diabetes, with hyperlipidaemia, with hypertension, with chronic venous diseases, with obesity-related metabolic syndrome or with cancer.

The compounds according to the invention are especially useful for the treatment, prevention and secondary prevention of myocardial infarction, angina pectoris, cerebrovascular accidents, aortic aneurysms, arteritis of the lower limbs, fibrotic diseases, venous thromboses and pulmonary embolism.

Vascular risk factors and vascular diseases such as hypertension, obesity, diabetes, cardiac diseases, cerebrovascular diseases and hyperlipidaemia, and therefore atherosclerosis, play a role in the genesis of dementias such as Alzheimer's disease and vascular dementia (Qiu C., De Ronchi D. and Fratiglioni L., The epidemiology of the dementias: an update, 2007, Current Opinion in Psychiatry, 20: 380-385). The compounds of the invention will therefore also be of use for the treatment and/or prevention of dementias such as Alzheimer's disease and vascular dementia.

TAFIa lowers endogenous fibrinolytic potential. As TAFIa inhibitors, the compounds of the present invention are therefore of use to accompany acute treatment by injectable fibrinolytics, such as recombinant tPA (for example alteplase, tenecteplase; reteplase, desmoteplase), recombinant uPA or streptokinase, which are used in emergencies (for example myocardial infarction, cerebrovascular accident).

The compounds of the present invention reinforce the activity of these injectable fibrinolytics and therefore lead to the use thereof with fewer haemorrhagic and neurotoxic risks (reduction of the dose thereof and therefore reduction of the side-effects thereof).

Intermediate 20b: tert-Butyl 3-{4[bis(tert-butoxycarbonyl)amino]butyl}-1-benzyl-4-ethoxy-4-oxo-1,4-azaphosphinane-3-carboxylate

DMSO (30 mL) and 60% NaH (8.48 g, 212 mmol, 1.5 eq) are introduced in succession, under an argon atmosphere, into a 1 L thee-necked flask equipped with mechanical stirring. The flask is maintained at ambient temperature by means of a water bath. A solution of intermediate 204 (54.6 g, 155 mmol, 1.1 eq) in DMSO (25 mL) is then added dropwise over a period of 5 minutes. A solution of intermediate 19 (50 g, 141.5 mmol) in DMSO (120 mL) is then added dropwise, the temperature being maintained below 20° C. When the addition is complete, 100 mL of anhydrous THF are then added in order that stirring can be maintained. After 3 hours, the reaction mixture is cooled by means of an ice-water bath and hydrolysed by addition of 500 mL of a saturated NH₄Cl solution. The mixture is then extracted with AcOEt (3×300 mL). The organic phases are then combined, washed with a saturated NaCl solution (2×300 mL) and dried over MgSO₄, before being concentrated under reduced pressure. The yellowish residue (92.5 g) so obtained is then purified by chromatography on silica gel using a CH₂Cl₂/AcOEt/MeOH mixture as eluant. The expected product (69.3 g, 110.9 mmol), a mixture of 4 diastereoisomers, is obtained in the form of a white solid with a yield of 78%.

Procedure E: Procedure for debenzylation by hydrogenolysis

Intermediate 21: tert-Butyl3-{4-[bis(tert-butoxycarbonyl)amino]butyl}-4-ethoxy-4-oxo-1,4-azaphosphinane-3-carboxylate

Intermediate 20b (73.6 g, 117.8 mmol), ethanol (1 L), Pd/C (7.36 g, 10% by mass) and 37% HCl (7.85 mL, 0.8 eq) are introduced in succession into a 2 L flask at ambient temperature and under a stream of argon. The argon is then replaced by a hydrogen atmosphere. The reaction is monitored by LC/MS. After 4 hours, the reaction is complete and the catalyst is filtered off over glass fibre. The filtrate is evaporated to dryness in order to obtain a yellow oil, which is taken up in AcOEt (400 mL) and in a 10% NaHCO₃ solution (400 mL). After decantation, the aqueous phase is extracted with AcOEt (3×100 mL). The organic phases are combined and then washed with a saturated NaCl Solution (400 mL), dried over MgSO₄ and concentrated to yield the expected intermediate 21 in the form of a white solid (57.6 g, 107.7 mmol) with a yield of 91%.

Procedure L: Procedure for Synthesis of the aldehydes Ar₂-Ar₁-CHO by a Suzuki Coupling

The non-commercial aldehydes were prepared in accordance with the procedure described below:

Ethanol (500 mL), boronic acid Ar₂-B(OH)₂ (92.7 mmol, 1.2 eq) and bromoarylaldehyde or bromoheteroarylaldehyde Br-An-CHO (77.3 mmol) are introduced in succession into a 1 L flask under argon and at ambient temperature. The solution is degassed with argon for 15 minutes. Pd(PPh₃)₄ (1.78 g, 1.55 mmol) and Na₂CO₃ (92.7 mL of a 2M solution in H₂O, 185 mmol, 2.4 eq) are then introduced in a single portion. After the addition, the reaction mixture is heated at reflux for 5 hours. The mixture is then evaporated to dryness. The residue is taken up in DCM (1 L) and H₂O (200 mL). After decantation, the aqueous phase is extracted with DCM (200 mL). The organic phases are combined and then washed with a saturated NaCl solution (400 mL), dried over MgSO₄ and concentrated under reduced pressure. The residue is then purified by flash chromatography on silica gel. The expected product is obtained with yields of from 59 to 94%.

Procedure F: Generic Procedure for Reductive Amination Starting from Intermediate 21 (Synthesis of Intermediates 22 to 127).

Intermediate 21 (14 g, 26.2 mmol), anhydrous DCM (280 mL), the aldehyde (intermediates 213 to 293) (39.3 mmol, 1.5 eq) and MgSO₄ (14 g) are introduced in succession into a 500 mL three-necked flask at ambient temperature and under a stream of argon. After stirring for 1 hour, NaBH(OAc)₃ (8.32 g, 39.3 mmol, 1.5 eq) is added in portions and the reaction mixture is maintained at ambient temperature for 16 hours. The reaction is monitored by LC/MS. The insoluble components are filtered off over microfibre and rinsed with DCM (100 mL). The filtrate is then washed with water (1×200 mL) and then with a saturated NaCl solution (2×200 mL). The organic phase is dried over MgSO₄ and concentrated under reduced pressure. The oil obtained is then purified by flash chromatography on silica gel (330 g) to yield intermediates 22 to 127.

Procedure G: Chiral Separation of the Diastereoisomers of Intermediate 20b

Intermediate 128: tert-Butyl (3S)-3-{4-[bis(tert-butoxycarbonyl)amino]butyl}-1-benzyl-4-ethoxy-4-oxo-1,4-azaphosphinane-3-carboxylate

DMSO (30 mL) and 60% NaH (6.78 g, 186.6 mmol, 1.6 eq) are introduced in succession under an argon atmosphere into a 1 L three-necked flask equipped with mechanical stirring. The flask is maintained at ambient temperature by means of a water bath. A solution of intermediate 204 (41.1 g, 116.7 mmol, 1.1 eq) in DMSO (25 mL) is then added dropwise over a period of 5 minutes. A solution of intermediate 19 (37.54 g, 106 mmol) in DMSO (100 mL) is then added dropwise, the temperature being maintained below 20° C. The addition in fact causes pronounced heating as well as pronounced thickening of the reaction mixture. When the addition is complete, 100 mL of anhydrous THF are then added in order that stirring can be maintained. After 3 hours, the reaction mixture is cooled by means of an ice-water bath and hydrolysed by addition of 500 mL of a saturated NH₄Cl solution. The mixture is then extracted with AcOEt (3×300 mL). The organic phases are then combined, washed with a saturated NaCl solution (2×300 mL) and dried over MgSO₄, before being concentrated under reduced pressure to yield a yellowish solid (69.94 g), a mixture of 4 diastereoisomers. The 4 diastereoisomers of intermediate 20b are separated on a 2.5 kg chiral column of type (R,R)-Whelk-O-1 in batches of 8 g, each batch requiring 2 passes under the following conditions:

1st Pass:

The mixture containing the 4 diastereoisomers of intermediate 20b (8 g of crude product) is applied to a chiral column of type (R,R)-Whelk-O-1 of 2.5 kg using as mobile phase DCM/heptane (55:45)+10% NEt₃ in order to isolate diastereoisomer 4 (number allocated according to the order of discharge from the column) of intermediate 20b.

2nd Pass:

The mixture containing the remaining 3 diastereoisomers of intermediate 20b is applied to a 2.5 kg chiral column of type (R,R)-Whelk-O-1 using as mobile phase MTBE+10% DEA in order to isolate diastereoisomer 2.

After 9 injections, the fractions containing diastereoisomers 2 and 4 of intermediate 20b are then collected and evaporated under reduced pressure to yield intermediate 128 (25.2 g, 40.3 mmol), quaternary carbon of the (S) configuration with a yield of 38%.

Intermediate 129: tert-Butyl (3S)-3-{4-[bis(tert-butoxycarbonyl)amino]butyl}-4-ethoxy-4-oxo-1,4-azaphosphinane-3-carboxylate

Intermediate 128 (30.35 g, 48.6 mol), ethanol (200 mL), Pd/C (3.03 g, 10% by mass) and 37% HCl (3 mL, 0.8 eq) are introduced in succession into a 500 mL flask at ambient temperature and under a stream of argon. The argon is then replaced by a hydrogen atmosphere. The reaction is monitored by LC/MS. After 4 hours, the reaction is complete and the catalyst is filtered off over glass fibre. The filtrate is evaporated to dryness in order to obtain a yellow oil, which is taken up in AcOEt (200 mL) and in a 10% NaHCO₃ solution (200 mL). After decantation, the aqueous phase is extracted with AcOEt (3×100 mL). The organic phases are combined and then washed with a saturated NaCl solution (400 mL), dried over MgSO₄ and concentrated to yield intermediate 129 in the form of a white solid (23.12 g, 43.24 mmol) with a yield of 89%.

Procedure H: Synthesis of the azaphosphepanes

A solution of N-Boc allylamine (30 g, 190 mmol) in THF (170 mL) is added dropwise to a 60% NaH suspension (11.45 g, 285 mmol, 1.5 eq) in THF (100 mL) and under an argon atmosphere. The mixture is left in contact for 1 hour 30 minutes, and then benzyl bromide (34 mL, 285 mmol, 1.5 eq) in solution in THF (30 mL) is added.

Pharmacological Study Example 264 Inhibition of TAFIa (hippuryl-Arg Test)

Human TAFI (4nM) is incubated with human thrombin (10 nM) and human thrombomodulin (5 nM) in the presence of calcium (10 mM). After incubation for 20 minutes, the activation reaction is stopped by addition of PPACK (1 μM final), an irreversible thrombin inhibitor. The reactions take place in Hepes buffer (25 mM Hepes, 137 mM NaCl, 3.5 mM KCl)+0.1% bovine albumin, pH 7.4 at 28° C. and with stirring.

The test compound is added to the solution of TAFIa (2 nM) and incubated for 45 minutes in the presence of hippuryl-arginine (5 mM). The reaction is stopped by addition of hydrochloric acid (1M) neutralised subsequently with sodium hydroxide (1M), and then the mixture is buffered with disodium hydroxyphosphate (1M pH 7.4). The reaction product—hippuric acid —is revealed by addition of cyanuryl chloride (6%). The reaction mixture is stirred (vortex) and then centrifuged. The supernatant is transferred to a 96-well microplate, and the absorbance is measured using a spectrophotometer at 405 nm (Spectramax plus, Molecular Devices).

The OD value of a well containing the reagents without TAFI is subtracted from all the OD values measured. The percentage inhibition of TAFIa at a given concentration of the test compound is determined by means of the following formula:

% inhibition=100−[(OD compound×100)/OD carrier]

The compounds are evaluated at 10 nM and 20 nM under the experimental conditions described above and the results are expressed as the percentage inhibition relative to a control containing the carrier in the absence, of compound.
